I am running ZMailer router (2.99.48p3 #1: Thu May 29 15:21:13 EDT 1997)
I have not seen any postings to the list that address this problem
since the last time I reported it. the hold transport agent
is looping (truss output is below) on Sunos5.5.1. Not only is
it looping, but I just killed it this morning due to the fact
that is 124MB in size. I believe this is reproducible. mailq
shows the following:
hold/*/0
hold/ns:uhavax.hartford.com/any/0 R=1 A=3046743 P=13456 HA=1s FA=1s OF=1
QA=1d4h
hold/ns:ns1.chinaonline.com.cn.net/any/0 R=1 A=2 W=2960s QA=55m6s

doing an nslookup shows both of these having non-existant domains.
